[[folder: The Institute]]

!!Theresa "Tessa" Gray

Tessa has spent the first sixteen years of her life being overprotected by her aunt after [[ParentalAbandonment the death of her parents in a carriage accident]]. She lives almost all her life in books, [[GenreSavvy dreaming of having the kind of adventures the heroines she reads about do]]—until she is forced to travel from New York to London when her brother Nathaniel goes missing and only a pair of mysterious—and sinister—women called the [[NamesToRunAwayFromReallyFast Dark Sisters]] seem to know where he might have gone. The Shadowhunters of the London Institute may be Tessa's only hope of finding Nate, but their mysterious world of demons and Downworlders holds many dangers for her—especially when she realizes she might be more a part of it than she'd thought.

%% * AllGirlsWantBadBoys / SingleWomanSeeksGoodMan: Will and Jem respectively.
* ArrangedMarriage: Tessa was going to be forced to marry the Magister had she not been rescued by Will. She was obviously not very happy about it.

* ChekhovsGun: [[spoiler: Will's mention of Boadicea gives Tessa the strength to fool the Magister.]]
* ChekhovsGift: [[spoiler: The clockwork angel. Also, Tessa's dislike of chocolate and the [[PerfectPoison gift]] Nate gives Aunt Harriet...]]
%% * ConvenientlyAnOrphan
%% * DeadpanSnarker
%% * DeceasedParentsAreTheBest
* DrivenToSuicide: Subverted. [[spoiler: She makes the Magister ''think'' she killed herself so that he wouldn't get his hands on her power, but in reality she Changed into a woman who'd died by a gunshot wound seconds before the wound would prove fatal.]]
* {{Expy}}: Of ''Fanfic/TheDracoTrilogy'' version of [[Literature/HarryPotter Hermione Granger]] .
* FakingTheDead: In ''The Clockwork Angel'', [[spoiler:she fakes her own suicide to prevent Mortmain from using her power.]]
* FirstKiss: [[spoiler: William Herondale in the attic.]]
%% * GenreSavvy: Because she's so wide-read.
* GoodAngelBadAngel: Played with by having Jem and Will be Tessa's angels, respectively. It doesn't hurt that they're both part angel.

%% * TheHero
* InterspeciesRomance: With both Will and Jem.

* ParentalAbandonment: Her parents died when she was three.

** DeadPersonImpersonation: She can do this.
** {{Humanshifting}}: This is her unique power. Her whole schtick is that she can change her appearance into any humanoid, dead or alive, as long as she has touched an object that belonged to them. She's turned into both males and females.
** NotQuiteBackToNormal: She worries that this would happen eventually.
** ShapeshifterDefaultForm: Her normal body, of course.

!!William "Will" Herondale

Seventeen-year-old Will is the sort of young man [[AllGirlsWantBadBoys nice Victorian girls were warned against]]. He drinks, gambles, and enjoys the company of ladies of questionable virtue—at least, as much as he enjoys anything. Will hates everyone and everything, with the possible exception of Jem, and even that's in some doubt. Charlotte despairs of keeping him alive past the age of nineteen. When he finds himself oddly drawn to Tessa, his friends begin to hope that the Downworlder girl will prove Will's unlikely salvation—but as Tessa grows closer to the bleak secret that makes his life a prison, danger threatens to destroy them both if she ever finds out the truth.

* AllGirlsWantBadBoys: Will constantly says he's always out drinking and gambling, and that there are a dozen girls who've claimed that he'd compromised their virtue. [[spoiler:Jem, however, thinks he's lying to make himself look bad.]]
* ButNotTooForeign: He's half English and half Welsh. His actual name is Gwilym, but this is only brought up once or twice in passing and for some reason he seems to prefer to be called by his "British" names.
%% * ByronicHero
* CartwrightCurse: [[spoiler: A variation that just doesn't cover {{Love Interest}}s. When he was younger, Will opened a Pyxis and ended up being cursed such that anybody who cares for him will die. Or at least, [[BlatantLies that's what the demon]] [[SubvertedTrope told him.]]]]
%% * CassandraTruth: [[spoiler: The existence of demon pox.]]
%% * TheCharmer
* ChronicHeroSyndrome: According to Jessamine, Will thinks he's [[KingArthur Galahad]]. And it's true.
* DarkAndTroubledPast: Or at least, he alludes to one quite often.
* DeadpanSnarker: Oh, ''Will.''
--> '''Gabriel''': You know, there was a time when I thought we could be friends.
--> '''Will''': There was a time when I thought I was a ferret, but that turned out to be the [[OpiumDen opium haze]]. Did you know it had that effect? 'Cause I didn't.
** And there's this scene from ''The Clockwork Prince'':
--> “They’re not hideous,” said Tessa.
--> Will blinked at her. “What?”
--> “Gideon and Gabriel,” said Tessa. “They’re really quite good-looking, not hideous at all.”
--> “I spoke,” said Will, in sepulchral tones, “of the pitch-black inner depths of their souls.”
--> Tessa snorted. “And what color do you suppose the inner depths of your soul are, Will Herondale?”
--> “Mauve,” said Will.
* EmoTeen: According to fans. He even lampshades it himself at times.
* EvenTheGuysWantHim: De Quincy and Magnus Bane both hint at this about him.
* {{Expy}}: Of the Fanfic/DracoTrilogy version of [[Literature/HarryPotter Draco Malfoy]] .
%% * {{Foil}}: To Jem.
%% * TheGamblingAddict
* HeterosexualLifePartners: With Jem. So much that even though both boys love Tessa, they are willing to let the other one have her and even if Jem died after marrying Tessa, Will would never pursue Tessa as he feels it would be a betrayal to his friend.
* HiddenHeartOfGold: [[spoiler: It's to stop people from caring about him too much - because of his curse, they'll wind up dead eventually. After he finds out that there is no curse, he mellows down.]]
* HollywoodAtheist: [[GratuitousLatin Pulvis et umbra sumus.]] For those who don't read Horace, that means "we are dust and shadows," pretty much said by Will to be what he believes in.
* IWantMyBelovedToBeHappy: [[spoiler:Pulls this for ''both'' Tessa and Jem when they announce their engagement.]]
* ISeeDeadPeople: Confirmed in the first chapter of ''The Clockwork Prince'' to be one of the few Shadowhunters that can.
* InterspeciesRomance: With Tessa.
%% * InsecureLoveInterest
* JadeColoredGlasses: He alludes to a traumatic childhood quite often.
* JerkAss: He very occasionally strays into JerkWithAHeartOfGold territory, but he really isn't. However, [[spoiler: he does shift into HiddenHeartOfGold territory after the discovery that he ''literally'' kills everyone he loves. Until it turns out that he doesn't. He's still distant, though, but that's just his personality.]]
%% * TheLancer
%% * MoodSwinger
* MrFanservice: Big time. Will's good looks are given a lot of attention.
* OddFriendship: With Jem - Will is a rude asshole and Jem is a kindhearted nice guy. They even ''look'' absolutely different: Jem is all white and silver and Will is all dark colors.
* PlayingDrunk: [[spoiler:Jem says it's to make himself look bad. It is revealed in ''The Clockwork Prince'' [[CartwrightCurse why]].]]
%% * RavenHairIvorySkin
%% * SensitiveGuyAndManlyMan: With Jem. No points for guessing which one he is.
%% * StockForeignName
%% * TroubledButCute
* WhatBeautifulEyes: His dark blue eyes are one of his most striking features.

!!James "Jem" Carstairs

Brought up in the [[ButNotTooForeign Institute in Shanghai]], Jem's parents were [[spoiler: [[DarkAndTroubledPast killed by a demon who allowed Jem to live]]]]—but with [[SoapOperaDisease a terrible price to be paid]]. [[IllBoy Frail]] and silver-haired, Jem seems an unlikely demon-killer, but his skills and swift intelligence make him a formidable foe. He finds a kindred spirit in Tessa as both of them feel they are torn between two worlds, neither belonging completely to one or to the other. As Jem's affection for her grows, will Will have to hurt the only person in his life he's ever seemed to care about?

%% * BewareTheNiceOnes
* BloodFromTheMouth: Due to his 'illness', he coughs up blood when weak.
* ButNotTooBlack: According to Creator/CassandraClare, an early cover for one of the ''The Clockwork Prince'' him pulling his hat over his face. The cover was changed when Clare protested.
* ButNotTooForeign: He's half English and half Chinese[[note]]which was unusual for the time period given the state of relations between Britain and China[[/note]]. His actual name is Jian, but this is only brought up once or twice in passing and for some reason he seems to prefer to be called by his "British" name.
* ChronicHeroSyndrome: According to Jessamine. Not as much as Will, though.
%% * ConvenientlyAnOrphan
* DarkAndTroubledPast: [[spoiler: A demon who had a grudge against his mother tortured him in front of his parents, injecting him over and over with a drug that made him hallucinate vividly. See SoapOperaDisease.]]
* DeadpanSnarker: His snarkiness comes mostly from saying something, then adding "Not really" with something humorous. He can play the trope completely straight, though.
* DefinitelyJustACold: To Tessa when she asks about his health.
* DiseaseBleach: [[spoiler:Turns out it's because of a demonic halluginogenic drug originally used to torture him as a child.]] Same goes for his eyes.
* ElegantClassicalMusician: He can play the violin, and quite well, too.
* {{Expy}}: Of the Fanfic/DracoTrilogy version of [[Literature/HarryPotter Harry Potter]].
%% * {{Foil}}: To Will.
* FullNameUltimatum: A partial version of this trope; Will is the only one to call him, "James", although it is a mark of affection more than anything.
%% * GentlemanSnarker
* [[ICantBelieveAGuyLikeYouWouldNoticeMe I Can't Believe A Girl Like You Would Notice Me!]]: To Tessa, [[spoiler: after she accepts his proposal.]]
* [[IllGirl Ill Boy]]: He has to take a drug to battle a disease he got from being tortured as a child and coughs up blood if he goes too long without it.
* IncurableCoughOfDeath: His illness that causes him to cough up blood. No cure has been found. [[spoiler:That is until the epilogue of ''The Clockwork Princess'', where a cure was finally found.]]
* InterspeciesRomance: With Tessa.
* JadeColoredGlasses: Subverted. [[spoiler: He had a very traumatic experience but seems to function perfectly normally outside his "illness".]]
* KindheartedCatLover: When he adopts Church.
* MementoMacGuffin: His mother's family ring, which [[spoiler: he uses to propose to Tessa.]]
* MoralityPet: For Will.
%% * NiceGuy
%% * [[spoiler: NiceGuysFinishLast: Subverted/Averted/Inverted? Depends on how literal you take the name.]]
%% * TheNotLoveInterest: For Will.
* ObliviousToLove: Probably can't tell that Sophie's sweet on him.
* OddFriendship: With Will - Jem is a kindhearted nice guy and Will is a rude asshole. They even ''look'' absolutely different: Jem is all white and silver and Will is all dark colors.
* SecretlyDying: As of ''The Clockwork Prince'', [[spoiler:he is still hiding his SoapOperaDisease from everyone except Will and Tessa.]]
%% * TheSmartGuy of the FiveManBand
%% * SensitiveGuyAndManlyMan: The Sensitive Guy to Will's Manly Man, Will's tendencies often making him look near-saintlike in comparison.
* SoapOperaDisease: [[spoiler: It was caused by a demon drug that was used to torture him and his parents when he was younger. There is no known cure for it, and he has to keep taking a specific drug to keep on fighting - as Brother Enoch says, taking the drug means a slow death, but keeping him off the drug would mean a quick one.]]
%% * StockForeignName
* SwordCane: His WeaponOfChoice is a jade-tipped one.
* TechnicolorEyes / GrayEyes: Jem's eyes, [[CurtainsMatchTheWindow like his hair]], are silver.
* TokenMinority: He's part Asian.
* YouGottaHaveBlueHair: His hair is described as silver.
* YourDaysAreNumbered: He is [[spoiler: addicted to a drug (yin fen) that is slowly killing him. However, to stop taking the drug will also kill him.]]

!!Charlotte Branwell (nee Fairchild)

[[ImprobableAge Twenty-three-year-old]] Charlotte runs the entire Institute with a capable hand. [[TeamMom Kind and loving, she does her best to care for the orphaned Shadowhunters who live under her roof]] while hiding her loneliness from the absent-minded husband she loves. It seems as if there's nothing Charlotte can't manage—until Tessa's search for her missing brother begins to uncover a web of corruption and deceit in London's Downworld that threatens to tear London's Conclave of Shadowhunters apart.

%% * ActionGirl
* BrainyBrunette: Charlotte is ''very'' intelligent.
%% * TheChick
* DeadlyDisc: Uses two on the battle after Blackfriar Bridge.
%% * HappilyMarried: With Henry, more or less, despite his awkward GeniusDitz-ness.
%% * HugeGuyTinyGirl: Tiny girl to Henry's huge guy.
* InTheBlood: It's mentioned in passing that her father was the previous caretaker of the Institute.
* LikeASonToMe: It's almost as if Will, Jem, and Jessamine were her own children, except, according to her, [[TheWoobie for the part where they were required to love her]].
* ParentalSubstitute: Raised Will, Jem, and Jessie since they came to the institute. Will says that she would have been called a governess had she not been so intelligent and if she didn't have the ability to chop one into pieces.
* PregnantBadass: [[spoiler:As of the end of ''The Clockwork Prince''.]]
* TeamMom: Her main function is basically making sure everybody doesn't kill everybody.
* YoungerThanTheyLook: Charlotte's small size is countered by the air of competence she exudes, and Tessa says she had assumed her to be ''much'' older than twenty-three.

!!Henry Branwell

Absent-minded and brilliant, Henry spends his waking hours in the crypt of the Institute, [[GadgeteerGenius inventing fabulous machines and weapons out of cogs cams and gears]]. Unfortunately just as many of Henry's inventions don't work as the ones that do, and Henry is as [[GeniusDitz likely to set himself on fire as he is to invent something new and amazing]]. When Tessa finds herself followed by a silent band of assassins who turn out to be automata—[[ClockworkCreature human beings made from clockwork parts]]—it is Henry who must decipher how they work in order to find the demonic mechanical genius at the heart of the most evil plan London's supernatural world has ever seen.

* AbsentMindedProfessor: While not really being a professor in the first place. But he's a brilliant inventor who just happens to forget things.
%% * TheBigGuy
%% * BunglingInventor
%% * BunnyEarsLawyer
* GadgeteerGenius: His defining character trait.
* GeniusDitz: ''Big time'' - Henry is as absentminded as they come, but when it comes to mechanical stuff, he's your guy.
%% * HappilyMarried: To Charlotte, more or less.
%% * HugeGuyTinyGirl: Huge guy to Charlotte's tiny girl.
* PhlebotinumBreakdown: What most of his inventions end up doing.

!!Jessamine Lovelace

Jessamine's parents, like Will's were Shadowhunters who left the Clave. [[ParentalAbandonment Their deaths in a fire orphaned her]], leaving her to be brought up in the Institute by Charlotte and Henry. Jessamine hates everything about being a Shadowhunter, from the training to the danger to the existence of demons, which she sees as "smelly and disgusting." Armed with a [[ParasolOfPain razor-edged parasol]] and an [[DeadpanSnarker equally sharp tongue]], Jessamine can be dangerous if she wants to be—to herself as much as to the supernatural creatures she's sometimes forced to encounter.

* CrouchingMoronHiddenBadass: [[spoiler:Despite trying all she can to be TheLoad, she can't deny her Shadowhunter heritage.]]
%% * DeadpanSnarker
%% * DeceasedParentsAreTheBest
* DontYouDarePityMe: In ''Clockwork Prince''.
* DumbBlonde: Subverted. While flouncy and just a tad spoiled, Jessamine is a perfectly capable Shadowhunter in her own right.
* EnglishRose: Tessa Gray is a New Yorker who travels to VictorianLondon, and she describes Jessamine as one. She strives to be a Proper Lady and has many lady-like attributes (like her ParasolOfPrettiness), but ultimately she fails to be a straight example because she's something of a SpoiledBrat.
* EtTuBrute: [[spoiler:She betrays the Institute for Nate.]]
* TheFashionista: Jessamine is ''very'' concerned about how she looks, and it's she who takes Tessa out to buy new dresses.
* IJustWantToBeLoved: Implied to be her motivations for her actions in ''The Clockwork Prince''.
* ImprobableWeaponUser: She uses a ''parasol'' Henry made for her. The fabric is edged with electrum, though.
* InterspeciesRomance: She develops feelings for Tessa's brother, Nate, though this may just be out of her desire to be a Mundane.
* TheLoad: Played with. [[spoiler: She ''actively tries'' to be this due to her hatred of being a Shadowhunter, but she also demonstrates that she's a very capable fighter.]]
* LoveFreak / InLoveWithLove: She wants someone to take her away from the Institute.
* LoveMartyr: [[spoiler:For Nate - she continues to feed him information despite Tessa's repeated insistence that he loves no one but himself.]]
%% * TheMole: [[spoiler:In ''The Clockwork Prince''.]]
* ParasolOfPrettiness: Aw, look at Jessamine's parasol! It's so pretty and pink and it even has flowers on it...
** ParasolOfPain: ...and the edges are laced with electrum. ''Ouch''.
* ProperLady: Strives to be this. She fails because of her attitude.
* RazorFloss: Edges her parasol, turning it into an effective weapon.
* ReluctantWarrior: Although she's no ActualPacifist. She just really, ''really'' hates the Shadowhunter world.
* SecretRelationship: [[spoiler:With Nate in ''Clockwork Prince''.]]
%% * TheSixthRanger: Due to her dislike of the Shadowhunter world.
%% * SixthRangerTraitor: [[spoiler:She betrays the Institute because of her love for Nate.]]
%% * SpoiledBrat: More or less.

[[folder: Other Shadowhunters]]

!!Benedict Lightwood
One of the older members of London's Enclave and Gabriel's father. Benedict questions Charlotte's ability to run the Institute.

* BalefulPolymorph: [[spoiler:In ''The Clockwork Princess'', he is gradually driven mad and finally turned into a gigantic serpent-like demon as a result of the demon pox.]]
* DoesThisRemindYouOfAnything: [[spoiler: Demon pox is the Shadowhunter version of HIV or syphilis.]]
* HeelFaceTurn: [[spoiler: He withdraws his challenge to Charlotte's leadership, so she won't reveal to the Clave that he has demon pox.]]
* InterspeciesRomance: [[spoiler:With an unknown number of Demonesses]]
* {{Jerkass}}: He knowingly infected his wife with demon pox.
* StayInTheKitchen: One of his claims against Charlotte's leadership is that women are incapable of running the Institute.
* TragicMonster:[[spoiler: Well, YMMV on this, but his sons were forced to kill him after he turned into a giant serpent.]]

!!Cecily Herondale
William's younger sister who [[spoiler: arrives at the Institute at the end of Clockwork Prince.]]

* ActionGirl: [[spoiler: She assists in killing the demon Benedict Lightwood turned into]].
* AffectionateNickname: She is called "Cecy" by Will and later [[spoiler:Gabriel Lightwood.]]

* HotBlooded: Will describes her as being stubborn
%% * PluckyGirl
%% * RavenHairIvorySkin
* StrongFamilyResemblance: With her brother Will and their mother.
* WhatBeautifulEyes: Has dark blue eyes like her brother.

!!Gabriel Lightwood
Benedict's younger son and Will's apparent rival.

%% * ArrogantKungFuGuy
* BigBrotherInstinct: Will says the reason Gabriel hates him so much is because he compromised the latter's sister's virtue. But then again, it's [[ConsummateLiar Will]], so we don't know if that's true or not. As of the second book, it's apparently because Will rejected his little sister's advances (in his defense, she was a lovesick twelve-year-old) and broke Gabriel's arm in public.
* HeelFaceTurn: [[spoiler:He stops supporting his father after his father is turned into a demon by the demon pox.]]
* HotBlooded: In direct contrast to his brother, Gideon, who is TheStoic.
* JerkAss: Quite blatantly.
* JerkWithAHeartOfGold: He's surprisingly patient with Tessa while training her. Of course his {{Jerkass}} side comes out when he's frustrated and he is prone to taking out his anger on other people. He becomes much nicer in ''The Clockwork Princess'' when [[spoiler:his father is turned into a demon as a result of demon pox and he is forced to stay at the Institite.]]
* TheRival: Presumably to Will. [[spoiler: They gradually learn to respect each other in ''The Clockwork Princess''. Will doesn't have much of a choice, his younger sister ends up marrying Gabriel.]]
* SiblingYinYang: With Gideon.
* SitcomArchnemesis: From what we've seen, he is this to Will.
* ThickerThanWater: Gabriel puts strong emphasis on staying loyal to family. [[spoiler: At the end of ''The Clockwork Prince'', Gabriel chooses to stay with his father while his older brother Gideon deserts him for the Institute.]] [[spoiler: In ''The Clockwork Princess'', he finally understands that he was wrong to trust his father so much.]]

!!Gideon Lightwood
Gabriel's older brother, who returns from Spain in the second book.

* BigBrotherInstinct: Towards his younger brother, Gabriel.
* DeadpanSnarker
* GratuitousSpanish: {{Justified}} given that he did spend time in Spain, so he probably picked up some of the language.
* [[GrayEyes Gray]]-Green Eyes: Gray for his calmness, Green for his Shadowhunter powers.
* InformedFlaw: Is supposedly an even bigger {{Jerkass}} than his little brother, although he's shown himself to be nicer than Gabriel. Considering that was Will speaking, it's no wonder[[note]][[CharacterDevelopment He ''was'' possibly a bigger asshole than Gabriel, but he shaped up during his time in Spain]][[/note]].
* InterspeciesRomance: With Sophie. [[spoiler: At least until she ascends and becomes a shadowhunter herself.]]
* {{Jerkass}}: It's possible that he used to be this, but in ''The Clockwork Prince'', it appears he got better while he was in Spain.
* SiblingYinYang: With Gabriel.
* StarcrossedLovers: [[spoiler: Him and Sophie.]]
* TheStoic: He is a lot calmer than his brother Gabriel.

[[/folder]]

[[folder: Other Downworlders]]

!!Lady Camille Belcourt

* TheBeautifulElite: Camille is a vampire, so [[VampiresAreSexGods naturally]] this would come into play.
* DumbBlonde: Very much averted.
* ForegoneConclusion: We already know that her and Magnus's relationship isn't going to last long.
* InterspeciesRomance: With Magnus Bane [[spoiler: and, previously, a werewolf, which de Quincey frowned upon, because, you know, [[FurAgainstFang vampires and werewolves are supposed to loathe each other.]] Camille ''really'' started hating de Quincey after he murdered her werewolf lover.]]
* LadyOfWar: As a vampire, Camille can fight, but as a lady of high social standing she carries herself with a dignified manner. Tessa has difficulty imitating her during TheInfiltration.
* OurVampiresAreDifferent: She is very lovely.
* ProperLady: Behaves like this.
* VampiresAreRich: Naturally.

!!Alexei de Quincey
* EvilFormerFriend: To Camille. Apparently he still doesn't get the message that she doesn't see him as a friend - or anything else, for that matter - anymore, [[spoiler: not after he killed her werewolf lover.]]
* KilledOffForReal
%% * OurVampiresAreDifferent
* RedHerring: [[spoiler: he's not really the Magister]].
* TheScapegoat: In all honesty, de Quincey is not the poster boy for morality, [[spoiler: but he is certainly not the Magister.]]
* VampiresAreRich: Known to throw absolutely ''lavish'' parties [[spoiler: where they abuse mundanes]].

!!Magnus Bane

* BiTheWay: Although most initially know this from the Mortal Instruments series, this series shows it at first with certain comments he makes about Will upon first meeting him and Tessa, and later [[spoiler: makes it obvious when he is shown to have started a physical relationship with Woolsey Scott]]. He's certainly still quite [[CampGay campy]] even in this series.
* EvenTheGuysWantHim: De Quincy was interested in him, "as more than friends". Tessa ''didn't'' know what Magnus was hinting at, but that was because such things were ''unheard'' of in such a time period... (or just not talked about).
* InterspeciesRomance: With Camille and Woolsey Scott.
* LoveMartyr: Has shades of this for Camille.
* MarkOfTheSupernatural: He has cat eyes.
* TokenMinority: Like Jem, he's part Asian.
* TwoferTokenMinority: He is biracial (part Asian) and a self-proclaimed "freewheeling bisexual." And a warlock to boot.

!!The Dark Sisters

%% * NamesToRunAwayFromReallyFast
%% * SiblingTeam: A villainous example.
%% * ThemeNaming: Mrs. Dark and Mrs. Black. Gee.

A warlock whose help Charlotte enlists to keep tabs on the Herondale family.

[[/folder]]

[[folder: Mundanes]]

!!Sophie Collins
One of the servants at the Institute.

* DeadpanSnarker: Oh, so much. Especially to Will.
%% * GirlFriday: To Tessa.
* IfICantHaveYou: [[spoiler: The reason for her scar - the son of her previous employer wanted her and when she refused his advances, took a knife to her face so that nobody could have her beauty.]]
* InterspeciesRomance: With Gideon.
* ISeeThemToo: She has a touch of the Sight, which is how Charlotte let her work for them.
%% * {{Meido}}
* ObliviousToLove: Likewise, she had no idea that Thomas was sweet on ''her''.
* ScarsAreForever: She has a huge one running down the left side of her face that distorts her beauty. She seems to be more or less okay with it, though, saying that whoever would love her now wouldn't love her just for her looks.
* SlidingScaleOfBeauty: She is an Imperfect beauty example. She used to be beautiful and still is, but has a scar stretching across her face.
* StarcrossedLovers: [[spoiler: With Gideon.]]
* WhenSheSmiles: According to Tessa, Sophie has a downright ''amazing'' smile that makes her beautiful despite her scar.

!!Thomas Tanner
Another of the servants at the Institute.

* AlliterativeName: His surname is revealed to be "Tanner" as of the second book.
* TheBigGuy: Which is rather ironic, considering he was a shrimp when he was younger.
* TheDriver: Drives the carriage.
* ISeeThemToo: Has the Sight.
* ImpaledWithExtremePrejudice: [[spoiler:By an automaton.]]
* ItHasBeenAnHonor
* KilledMidSentence
* LastRequest: [[spoiler:He asks Will to take care of Sophie, because Sophie is...[[KilledMidSentence something]].]]
* LegacyOfService: He comes from a long line of people who've had a touch of the Sight, which is required for servants of the Nephilim. Needless to say, his family's been serving the Institute for a while.
* StuffedInTheFridge: [[spoiler: Killed by the automatons.]]

!!Agatha
The cook at the Institute.
* [[spoiler: StuffedInTheFridge]]
* TeamChef: Her food is excellent.

!!Nathaniel "Nate" Gray
Tessa's brother, who has gone missing at the start of the series.

* ConsummateLiar: The guy is ''really'' good at improvising tall tales, you have to give him that.
* EtTuBrute: [[spoiler:What's with the constant brother/sister betrayals in Cassandra Clare books?]]
* PrettyBoy: According to Tessa and Jessamine.
* ReallyGetsAround: Although, not explicitly stated, Tessa implies it in her conversation with Jessamine.
* TheUnfavorite: Subverted with his biological parents, but with if Aunt Harriet was ever supposed to pick which one of her sister's children would become more successful, it would be Tessa.

!!Axel Mortmain

* GadgeteerGenius: [[spoiler: It was ''he'' who created the [[RidiculouslyHumanRobots Ridiculously Human]] {{Clockwork Creature}}s.]]
* HappilyAdopted: When he was younger.
* MeaningfulName: ''Axel'' Mortmain makes mechanical devices. [[spoiler: And don't forget that ''Mortmain'' means "Hand of Death."]]

* LegacyOfService: He comes from a long line of people who've had a touch of the Sight, which is required for servants of the Nephilim. Needless to say, his family's been serving the Institute for a while.
* ReplacementGoldfish: For his brother. This actually bothers Sophie a bit.
* StrongFamilyResemblance: Resembles Thomas very much, both in appearance and demeanor, although Tessa says he's more indifferent.
* SuspiciouslySimilarSubstitute: [[spoiler:Is essentially an older Thomas, brought in to replace him after his death.]]

!!Bridget Daly

* ActionGirl: In spite of the fact that she's a mundane, she is a deadly fighter.
* BunnyEarsLawyer: She sings annoyingly depressing songs everytime she cleans, which always get on everyone's nerves...and as mentioned above, she's more competent in battle than most ''Shadowhunters''. Will actually commented that she makes more difference in battle than both Lightwood siblings.
* CrouchingMoronHiddenBadass: She's just a cook and someone who makes depressing poetry/songs, yet is arguably the best fighter who isn't of supernatural(werewolf, vampire, etc.). Even Will got stunned.
* ISeeThemToo : Has the Sight.
* LegacyOfService: Her family's served the Nephilim for generations.
* SupremeChef: Takes over the job from Agatha.
* SuspiciouslyAproposMusic: Likes to sing weepy ballads that tend to get on the Shadowhunters' nerves, and they've fallen into this once or twice.

* JerkAss: He very occasionally strays into JerkWithAHeartOfGold territory, but he really isn't. However, [[spoiler: he does shift into {{Jerkass Facade}} territory after the discovery that he ''literally'' kills everyone he loves. Until it turns out that he doesn't. He's still distant, though, but that's just his personality.]]

* JerkassFacade: [[spoiler: It's to stop people from caring about him too much - because of his curse, they'll wind up dead eventually. After he finds out that there is no curse, he mellows down.]]

* [[GrayEyes Gray]]-{{Green Eyes}}: Gray for his calmness, Green for his Shadowhunter powers.

* SubmissiveBadass: Can stay on equal footing with Gabriel for a while, although Gabriel will always beat him due to being a Shadowhunter.

%% * SpiritedYoungLady

* TheLoad: Played with. [[spoiler: She ''actively tries'' to be this due to her hatred of being a Shadowhunter, but she also demonstrates that she's a very capable in a fight.]]

* TheLoad: Played straight and subverted with Jessamine. [[spoiler: She doesn't want to do anything and makes herself into a load, but she also demonstrates that she's a very capable Shadowhunter.]]

* InterspeciesRomance: With Sophie. [[spoiler: At least until she ascends and becomes a shadowhunter herself.

%% * BritishAccents

* BritishAccents: He has a tendency to slip into his East End accent when outside the Institute.

* BritishAccents: Despite being from New York, he has one of these. He uses "oughtn't" on several occasions. You know, like every American.
** Consider the time period, though. It's not too hard to believe that the educated Gray siblings would use what they perceive as more refined word choice--even though it isn't, but merely British English vs. American--regardless of nationality.
